Question

A charge of `8 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `48 J` to `16 J`, what is the voltage between points A and B?

Answer 1

`W_(AB)=-4V`

Explanation:

`"It will be work if the electrical forces exerts a force on a charge between two point."`
`Delta W=q*V_b-V_A`
`V_(AB)=V_b-V_A`
`Delta W=q*V_(AB)`
`16-48=8*V_(AB)`
`-32=8*V_(AB)`
`W_(AB)=-4V`
